This paper presents a 3D software tool for the design and optimization of
cathodic protection systems for submerged structures.
It provides the corrosion
engineer with a powerful tool for managing operational costs, significantly
reducing expensive commissioning surveys and costly repairs, adding major
value to the cathodic protection business.
The software is entirely CAD integrated such that it can deal with 3D
CP-configurations of arbitrary complexity with parameterisation of all
The CP model is based on the potential model
describing the ohmic drop in the electrolyte (soil, water) with non-linear
boundary conditions that model the electrochemical reactions at anodes and
In this paper, it is explained why the Finite Element Method is used to solve
As an example the protection level of a hypothetical marine vessel
using impressed current cathodic protection (ICCP) systems will be investigated.
In addition, the underwater electric potential (UEP) of the vessel will be
cathodic protection simulations, ICCP, advanced software package,
Cathodic Protection (CP) systems are widely applied to buried and offshore
Most often, these CP systems contain a series of impressed current
and/or sacrificial anodes, sometimes placed at a remote distance from the
The entire configuration of the CP system and the structures
necessitate and justify the use of numerical simulations.
